Resource consumption and related waste production are still rapidly increasing all over the world, leading to social and environmental challenges and to the production of the so-called ‘wastescapes’. Peri-urban areas—in-between urban and rural territories—are particularly vulnerable and prone to develop into wastescapes because they are generally characterised by mixed functions and/or monofunctional settlements, as well as by fragmentation in a low-density territory that is often crossed by large infrastructure networks. Moreover, peri-urban areas are generally the selected locations for the development of plants for waste management. In this way, they are crossed by waste flows of a different nature, in a landscape of operational infrastructures and wasted landscapes. Implementing Circular Economy (CE) principles, interpreting waste and wastescapes as resources, is a way to significantly reduce raw material and (soil) resource consumption, improving cities’ metabolism. A circular approach can positively affect the spatial, social and environmental performances of peri-urban areas. However, the transition towards a CE presents many challenges. This article outlines an approach to address these challenges, presenting a co-creation process among researchers, experts and stakeholders within Living Labs (LLs) processes. LLs are physical and virtual spaces, aiming at the co-creation of site-specific eco-innovative solutions (EIS) and strategies. In the LLs, public–private–people partnerships are developed by applying an iterative methodology consisting of five phases: Co-Exploring, Co-Design, Co-Production, Co-Decision, and Co-Governance. This article presents a case study approach, analysing the co-creation methodology applied in two peri-urban living labs, located in the Metropolitan Areas of Naples (Italy) and Amsterdam (The Netherlands), within REPAiR Horizon2020 research project.

In this first chapter of the Book “Regenerative Territories. Dimensions of Circularity for Healthy Metabolisms”, the relation between circularity and space is explored. The main focus is the development over time, and in particular the way how spatial planning and strategies respond to new unpredictable urgencies and opportunities related with territorial metabolisms. In relation to space and time, 5 grand rules are explored as necessary to implement the transition towards Circularity: (1) The Circular Economy paradigm shift requires a socio-ecological perspective and looking beyond boundaries; (2) Circular Economy is based on systems thinking and territorial metabolism; (3) a Circular Economy calls for a renewed approach to the public domain and stakeholder involvement; (4) amplifying the definition of Circular Economy with the inclusion of wastescapes; and (5) Planning the Circular Economy as an open collaborative system. The paradigm shift of contemporary planning towards circularity is aimed to facilitate the capacity of cities to be adaptive and flexible to the speeding up of the biggest changes in the present-day society. Therefore, the relation between the various spatial scales is strictly interlinked to the time scales, as well as to the metabolic processes and Life Cycles of Territories. In this perspective, the “existing city” is a non-negotiable common heritage, the result of a “selective accumulation” of material and immaterial traces produced by the slow and progressive anthropic work in the territory. Contemporary spatial planning looks beyond boundaries. This concerns both the physical boundaries between areas or countries, both the boundaries of the various scale levels of solutions, of the interrelated networks, of the public space and, particularly, of their reciprocity. It induces the scrutinization of the underlying social needs and the finding of instruments that allow the spatial planning and renewed infrastructure to fit the changing social objectives such as sustainability and liveability. The territory of the Circular Economy is the city, as a complex and multidimensional organism. However, the most problematic field for experimenting with “circular planning” is the peri-urban territory consisting of urbanized areas, crossed by differentiated phenomena of settlement expansion beyond the limits of the countryside, which identifies rural and open space, traditionally coinciding with the limits of the city. A circular planning for the regeneration of the peri-urban identifies the waste spaces, the decay of the territory, the obsolescence and end of life of buildings, functions and urban parts now inadequate, namely wasted landscapes (wastescapes). The latter are both the result of metabolic transformations of the territory and generator of prospects and potential for rebalancing the material welfare of the city.

Creating a circular economy poses multiple challenges yet has social opportunity. It represents a key approach to implement the management of more sustainable waste flows to achieve win-win solutions consistent with the EU environment goals, and with the social-economic expectations. As part of the comprehensive outcomes of the EU funded research project REPAIR, the paper presents the results for new technological soils, designed with the aim of implementing the number of products coming from the recycling of both C&D waste and organic waste. The paper discusses the technical issues of this solution in the framework of the specific characteristic of its supply chain. The research aim is focused on the design approach, working on the new products and process at once. Further, the project highlights the importance of dedicated local networks for sharing knowledge in between different stakeholders and experts, and for promoting innovation at local scales.

Across Europe, the current system of waste management is responsible for environmental pollution, leading to the need of a transition towards a circular economy model, and towards systemic approaches for achieving sustainable objectives. Interpreting waste as resource-through the development of eco-innovative solutions-can play a positive impact on the quality of life and of the environment. REPAiR 1 research project proposes eco-innovative strategies, in order to co-design and assess solutions, involving a series of decisional problems that require the development of Spatial Decision Support System, described in their general structure and with a focus on the REPAiR project.

Contemporary metropolitan areas present landscapes in transition towards sustainability, showing a regenerative potential based on their own natural, aesthetic, social, eco-systemic characteristics. This is connected to forms of landscape regeneration, taking into account different structures: spatial features, economic forces, but also communities’ perceptions and imaginaries. This paper unpacks this general question by making reference to some experimentations in the Campania Region in the South of Italy, and by investigating the ecological dimension within an Urban Metabolism approach and through a Living Labs methodology, to achieve communities’ and institutional engagement in the co-creation of knowledgea and regeneration strategies.
